If the morbid phenomena of which her body was the theatre remained obscure and beyond the reach of her mind, they were clear and intelligible to certain creatures belonging to the same natural kingdom as themselves, creatures to which the human mind has learned gradually to have recourse in order to understand what the body is saying to it, as when a foreigner accosts us we try to find someone belonging to his country who will act as interpreter. These can talk to our body, and tell us if its anger is serious or will soon be appeased. Cottard, whom we had called in to see my grandmother, and who had infuriated us by asking with a dry smile, the moment we told him that she was ill: “Ill? You’re sure it’s not what they call a diplomatic illness?” He tried to soothe his patient’s restlessness by a milk diet. But incessant bowls of milk soup gave her no relief, because my grandmother sprinkled them liberally with salt (the toxic effects of which were as yet, Widal not having made his discoveries, unknown). For, medicine being a compendium of the successive and contradictory mistakes of medical practitioners, when we summon the wisest of them to our aid, the chances are that we may be relying on a scientific truth the error of which will be recognised in a few years’ time.
